Abstract
This paper defines the UK Infra-Red Telescope (UKIRT) Hemisphere Survey
(UHS) and release of the remaining ˜12 700 deg2 of
J-band survey data products. The UHS will provide continuous J- and
K-band coverage in the Northern hemisphere from a declination of 0°
to 60° by combining the existing Large Area Survey, Galactic Plane
Survey and Galactic Clusters Survey conducted under the UKIRT Infra-red
Deep Sky Survey (UKIDSS) programme with this new additional area not
covered by UKIDSS. The released data include J-band imaging and source
catalogues over the new area, which, together with UKIDSS, completes the
J-band UHS coverage over the full ˜17 900 deg2 area. 98
per cent of the data in this release have passed quality control
criteria. The remaining 2 per cent have been scheduled for
re-observation. The median 5σ point source sensitivity of the
released data is 19.6 mag (Vega). The median full width at half-maximum
of the point spread function across the data set is 0.75 arcsec. In this
paper, we outline the survey management, data acquisition, processing
and calibration, quality control and archiving as well as summarizing
the characteristics of the released data products. The data are
initially available to a limited consortium with a world-wide release
scheduled for 2018 August.
